  On the inhibition of HIV-1 protease by hydrazino-ureas displaying the N→CO interaction

  摘要：

  To create novel HIV-1 protease (HIV PR) inhibitors, we have extended our investigations of the N -> C=O interaction as a moiety that reproduces electrostatic properties of the transition state of peptidolysis. Consequently, we prepared a series of compounds with an unusual hydrazino-urea core. In polar protic media, these adopt solely a cyclic constitution displaying the interaction on one side of the molecule while offering a urea moiety on the opposite side meant to hydrogen-bond with the enzyme flaps. Each inhibitor candidate was obtained via a key series of three synthetic steps employing carbonyl-di-imidazole (CDI). It was thus possible to efficiently fuse two independent building blocks, a hydrazine and a protected aminoaldehyde in a convergent manner. NMR and UV analysis proved that all compounds, when dissolved in polar protic media, existed exclusively in the cyclic constitution exhibiting the N -> C=O interaction. In total, five inhibitor candidates were tested with HIV PR for their potency. The one carrying the least bulk in peripheral substituents showed the highest activity. Its very low molecular weight ( 365 g/mol) holds great promise for future improvements in affinity without violating Lipinski's rule of remaining within the limit of 500 g/mol. (C) 2009 Elsevier Ltd.
